PETER DILLON AND JOHN OLEARY, OF SHERBROOKE, QUEBEC, CANADA.

MACHINE FOR PLACING l-IEADS IN CANS.

SPECIFICATION forming' part of Letters Patent No. 233,079, dated October 12, 1880.

Application filed J une 26, 1880.

To all whom it may concern Be it known that we, PETER DILLoN and JOHN OLEARY, both of Sherbrooke, Province of Quebec, Canada, have invented an Improvelnent in Mechanism for Placing Heads in Cans, of which the following description, in connection with the accompanying drawings, is a specification.

This invention relates to mechanism forplacing or inserting the heads into the body parts of tin cans, such as are commonly used for canned corn and other articles.

Our invention consists, essentially, in the combination, with a holder for the can-body, of a device vfor supporting or holding the canhead, and a plunger arranged to be reciprocated in 'said holding device to force the head therefrom into the can-body, and means to op erate said plunger, substantially as hereinafter specied and claimed.

Figure l represen ts, in front elevation, a machine containing our improvements; Fig. 2, a section thereof, and Fig. 3 a section on a larger scale of a can-body and its heads inserted therein.

The bed-plate a, supported upon a suitable table, b, (partially shown,) has upon its upper side a concavity, or socket, or support, b', in which is placed the lower end of the can-body, which at its other or upper end is to receive a head. The bed a has mounted upon it two standards, c c, having adjustable collars c. These standards serve as guides for the crosshead d, having the socketed part or holder d2, that holds in place the upper end of the canbody e, and for the cross-head j', having the plunger f2, that acts on and forces the llanged head g from the holder d2 into the open end of the can-body.

The adjustable collars c determine the time at which the cross-head d shall stop in its descent, according to the length of the can-body, While the cross-head j' and its plungerj'z, con nected with the slide-rods h, continue to de scend more or less after the said cross-head c is stopped, and the said plunger forces the canhead g into the end of the can-body more or less. y

The slide-rods h have one set of adjustable collars, h2, by which to determine the descent l of the plunger and crossheadf, according to its position of rest upon the collars c.

(No model.)

the length ofthe can, and a second set of collars, h3, to strike and liftthe cross-head dfrom The slide-rods h, extended through suitable holes or openings in the bed-plate a, have their lower ends connected together by means of tie-bar y', held on the slide-rods by screwsj.

The interior of the holder cl2 has an annular recess, 2, to receive the upper open end of the can-body e, the said upper open end ofthe canbody resting against or very near the annular shoulder or Wall forming the upper part of the said annular groove.

The face or lower end of the plunger f2 is shaped, as in Fig. 2, to correspond substantially with the outer face of the head g.

The cross-headj`has a ring or eye, x, with which, in practice, Will be connected a rope or chain, 5, extended over pulleys 6 and 7, when a weight, 8, or spring may be applied, to thus lift the cross-heads and slide-rods h into the full-line position, Fig. 2, the dotted-line position, Fig. 1, corresponding therewith. The tie-bar j has an eye, j", with which, in practice, will be connected a rope or chain, 9, attached to a suitable treadle, 10. These ropes, weight, and treadle are shown in Fig. 2; but the ropes are broken out to save space on the drawings, and but part of the treadle, of usual construction, has been shown.

The normal position of the parts under the faction of the weight 8 is as in Fig. 2. In such position a can-body, e, has its lower end set into the recess or socket b. Then a head, g, is inserted within the holder until it rests against the bottom of the plunger f2. The flanged part g2 of the head so inserted in the holder d2 will pass above the groove 2, and the said flanged part will be acted upon and held in position by the head-detainer m, herein shown as an adjustable spring-held pin having a rounded end, it acting upon the said lange 'rictionally and keeping the head in position within the holder, so that it will be moved only when acted upon positively by the plunger.

The head having been placed in the holder d?, the operator will depress the treadle, tiebar, slide'rods, and cross-bars d f until the cross-bar d meets the collar c and the upper end of the can-body is within the annular groove in the holder cl2. Then as the slide- IOO rod, cross-bar, and plunger f2 are further depressed the plun ger f2 forces the head evenly and squarely out of the holder Within the open end of the can-body, the iianged end of the head being prevented from striking the edge of the can-bod y by reason ofthe annularsocket.

A can-head inserted in the Can-body as described is ready to be soldered therein at the suit-able time in any usual Way.

We shall describe in another application an apparatus for soldering` the head in the can? body, said application describing` mechanism differing from that shown in a United States Patent already granted to us, No. 209,569.

The socket b and the holder d2 each have a flaring mouth, to enable the ends of the canbody to readily enter the said parts and be centered.

- In testimony Whereofwe have signed our 3o names to this specification in the presence of two subscribing Witnesses.
